STRAINER.

Application filed June 8,

This invention relates to strainers of that class shown and described in my application No. 226,627, filed October 17, 1927, the present invention being an improvement on the strainer of my said application. In forming the foraininous inverted thinibledike body ot the strainer of my said application, by spinning it into shape from a blank consisting, of a perforated or foraniinous flat piece 01 netal, there is a tendency to close up the fine holes in the perforated blank, and this difficulty is avoided in the present invention by which the inverted thinibledike foraminous strainer is made from a blank having cut out portions leaving arms which may be bent into shape to form the thimble-like strainer. all will hereinafter more fully app In the drawing Fig. 1 is a sectional elevation of a strainer constructed in accordance with the present invention. F 2 is a p an view of the perforated blank from which the body of the strainer is formed. 3 a sectional detail *iew showing the strainer r parts separated iroin each other, and B 151. is a detail view of the clamping ring by w rich the body of the strainer re1novahl attached to the flange of the strainer head.

Referring to the drawing, 12 denotes a tube which is threaded at its upper end for the reception of a nut 13 which in turn is threaded for attachment to a pump or other part in connection with which the strainer is to be used. The tube 12 is constructed with an annular recess 1 which rece ves a sleeve-like part 15 of the strainer head 16 which is provided with an annular groove 17.

The torzuninous strainer body 18 formed from a perforated blank 18, shown in detail in Fig. 2, said blank being cut away to form tour wings or parts which may be readily bent into shape to form the inverted thimble like strainer body 18. vided wth an annular indenta in mounting the head, and when thus fitted 2111931 body will be attached ETED STATES PA'i hli'l" @FFICE.

THE GREIST The body 18 is prot-ion 19 which,
